Performing coitus with a female in the "doggie" position whilst using ones arms to vigorously push/pull their pelvis up and down one's cock. (the act resembling the motions of a roosting gorilla)

Referring to women who are sexually or romantically attracted to other women. Applies to both lesbians and bisexual women, as it is only the same-sex attraction that matters, not any other attractions the women may have.

Originates from the Greek poet Sappho, a bisexual woman from the Isle of Lesbos, from which we get the term lesbian.
